The Puerto Princesa Underground River is one of the largest subterranean estuaries of the world, where tides propagates over 5 km inside. The cave, consisting of over 30 km of giant galleries, hosts an extremely complex ecosystem based on the huge colonies of bats and swallows. Its natural singularity was recognized as World Heritage by UNESCO since 1999, while the first part of its navigable branch was transformed into a show cave since 1982. A peculiarity of this cave is that, even been visited by more than 300.000 people/year, no fixed structures at all have been installed inside PPUR, which therefore should be still considered a totally pristine cave.
